CROC offers the Virtual Data Center, a set of virtual computing resources available via both the Internet and through dedicated links to its customers, which allows customers to manage resources via a self-service portal and fully control all IT services in the cloud without dependence on the service provider. CROC provides virtual servers, data storage systems with storage hierarchy, networks and network services, and Internet access with a configurable firewall as part of the IaaS service. In addition, any customer can use a unique demo cloud service. Via the demo service, companies can quickly learn how IT services will operate in the cloud. After this testing phase, many customers decide to 'go cloud'.
